The provider method

    AnotherProvider.provide_some() -> ConcreteClass

provides for

    AnotherProvider.some = Resource(MoreConcreteClass, ResourceKind.OVERRIDE)

But the method's return type annotation 'ConcreteClass' is not compatible with
'MoreConcreteClass'
So the return type must be compatible with 'MoreConcreteClass'
